Marine heatwaves spark major climate change concerns
Extraordinary marine heat waves are defined as an Australian investigator as a call for awakening and caused concern about their long -term effects.
International research published in the Refereed Magazine Science, said that unprecedented underwater heat waves in 2023 may be emphasized beyond a level where ecosystems can heal.
From November 2022 to March 2023, the Southwest Pacific Heatwave in the Tasman Sea lasted longer than ever, triggering the alarm between others in the North Atlantic and Pacific and lasted longer than ever.
They caused great concern among scientists, New South Wales Associate Professor Alex, Alex, described it as a call to awaken events.
However, he warned against proposals reached.
“An overturning point will show that we have passed through a threshold and we have not come again, but at this point we do not know if it is true.” He said.
He said that the “unprecedented increase” at the temperature of the sea surface in 2023 continued until 2025 and suggested that there may be a long -term change.
This then causes more heat wave, coral bleaching and seaweed and algae forests to be destroyed.
“When these habitat species begin to deteriorate or disappear, this will obviously have knockout effects for the entire ecosystem,” he said.
Research published by academics from China’s Eastern Technology Institute in Science found that the 2023 sea heat waves disintegrated records due to their intensity, duration and dimensions.
“The extraordinary (sea heat waves) in 2023 can represent a major change in ocean and atmosphere conditions, which potentially shows an early signal of an overturning point in the world’s climatic system.” He said.
Scientists warned that the ecosystems of heat waves can emphasize “beyond healing thresholds” with the collapse of coal reef, the replacement of fish and the destabilization of polar ice layers.
CSIRO Climate leader Jaci Brown said that the findings are compatible with the work of the organization and that the increase in marine heat waves is an example of the effects of climate change.
“Sea heat waves are just one example of how our future will play the way we understand.” He said.
He called for monitoring and modeling how the future of the world will look above a decrease in greenhouse gas emissions.
“If we don’t, we can’t prepare and we’re entering the unknown with terrible results for our future food, health and safety.”
